  1. Thanks Deadwood, today is the first day since Xmas I have been able to work in the shed. Ordered a new pair of carburetor manifold rubbers, fitted and went through everything again and reset to the book. Runs well and smooth and starts / idles well, however still lacks the power I would expect. I have set the second carb to come in 8mm ( the book says 10 ).
  2. Ok this has just about got me beat. I started by setting both needles to the highest settings main 5/5 second 5/5 = good power! pulling up in second however ran like a dog and was so rich the fumes stung my eyes. So I reset the needles to the book, Main 3/5 second 3/5 = no power. Reset to main 4/5 second 4/5 = same, no power. Rest to main 4/5 second 5/5 = still no power although slight improvement, when setting idle the bike ran best with the air screw all the way in, leaving soot on rear gaurd? Any idea?
  3. AAAARRRRRGGGGGHHH!!! These dam [emoji90] things are sooo frustrating.
  4. Hi YHGEORGE, the manual doesn't actually refer to this setting at all, I did look. After reading your simple suggestion I re-read the entire section on carbs in fine detail and picked up that in the specifications the needle codes eg. 5C31-3/5 which I was reading simply as the code however I now think the code is 5C31 and the 3/5 refers to the needle setting. Thanks YHGEORGE.
  5. Hi guys, sorry my post was a poor explanation, but now I have the shop manual in front of me I will try again using correct part names. While setting the full throttle position I found the primary carb valve was protruding 2mm into the throat not 1mm higher, this was due to the wire drum assembly hitting the throttle cable mount/clamps, this is what I filed back a little allowing full throttle position. My starting issue was solved on another thread thanks to advise from patuca, I have a habit of opening the throttle slightly when kicking [emoji4], after following his starting instructions I had no problem. Yes I have lifted the needles to high as I wanted to see how the bike ran if I gave it as much juice as I could intending on fine tuning later if it worked, which it did with the above adjustments I got the desired results however now she is running rough as because the settings are so rich. I was also avoiding pulling and replacing the carbs as that sucks. Will drop the needles a notch at a time until I have it where it runs best. I have read these old girls prefer to run a little lean, is this your experience? Cheers.
  6. Thanks patuca your advice worked. Running rich so will follow justaskmenicely advice also, hope I get it right soon, pulling the carbies on this thing is murder.
  7. Thanks Patuca, good info thank you. I do have a habit of moving the throttle when kicking. If that doesn't help I will double check the settings on the secondary carb as I have set it pretty low 7mm..
  8. Hiya all, finally, after a few set backs had time to work on the resto project "Yamaha XT550" pulled the carbies and found that in the fully open position the lever was hitting the cable brackets inhibiting the slide from fully opening to spec, so did a bit of filing, next was raise the needles on each slide to maximum height, each needle has 5 slots held by a circlip to raise and lower, reset the float height and took her for a rap. Excellent, great increase in power however a pig to start cold and pretty much impossible hot. Anyone out there had experience tuning these dam dual carbies? I am thinking I have raised the needles to high and am flooding it?

  10. Thanks Otis0, I have spent a few hours on it. Yes I bought the bike with it's original shop service manual, a big part of why I purchased this particular bike. I have rebuilt a 2 stroke before ( 81 YZ465 ) but never a four stroke so am a little hesitant to tackle it, actually very, but I think if I commit I should be ok.
  11. 1982 XT550 I have been restoring for the last 8 months or so
  12. Thanks for your post Otiso. I have a little work to do to get things right by the sound of it. She is starting to look how I want but not quite there yet, but considering where I started I am pretty happy.
  13. Sorry all, that was my first attempt at a post. My question was to those with a 82/83 xt. Should I be able to pull up the front end in second? Or is this as good as it was and my memory misleads me?
  14. Just about finished restoring an 82 XT550 (pic attached) and am wondering if I need to rebuild the engine also. I recall these bikes to be power houses with a light front wheel in first, second and third, however my memories are 25 years old, and 30kg lighter
